Tsuruga Onsen in Tsuruga city, Fukui Prefecture, occupies one of Japan's most historically significant port cities, the primary Pacific gateway for trade with the Korean Peninsula and continental Asia throughout the Nara and Heian periods, when silk, bronze, and Buddhist scriptures arrived here before being transported overland to the ancient capitals of Nara and Kyoto. The sodium-bicarbonate spring water flows warm and smoothing, offering restorative baths to sailors, merchants, and modern visitors who come to explore the city's remarkable concentration of historical heritage sites, including the ancient Kehi Jingu shrine whose towering torii gate is among the largest wooden torii in Japan. The bay's moonlit beauty, celebrated in Japanese poetry since the Heian period, gives Tsuruga Onsen a literary resonance deepened by centuries of cultural association.

Insider tip — Tsuruga Onsen is located in the port city of Tsuruga on Wakasa Bay, a historically vital gateway where continental trade goods and Buddhist scriptures first entered Japan from Korea and China. The bicarbonate waters at 40°C flow into baths perched above a coastline where ferries once crossed to the continent, lending every soak a sense of deep historical resonance. The nearby Kehi Jingu, one of Japan's grandest Shinto shrines, is an unmissable morning stop.
